Today could be the start of a brighter, better life. It is what you make of it.
When your stbx moves back in, be yourself. Don't walk on eggshells trying to hard.
Some people find it weird after all I have been through with my stbx but he and I are really good friends now. Don't know how long that will last but for now, it is what I need. It makes the letting go and moving on so much easier.
